Essentials Help

My friend needs help with setting up his permissions with Essentials' spawn mob feature, he wants it so only he can spawn them but he can't figure out how to do it
(His build will be posted soon, I hope)

 

Code:

groups:
    Default:
        default: true
        info:
            prefix: ''
            suffix: ''
            build: false
        inheritance:
        permissions:
    Moderator:
        default: false
        info:
            prefix: ''
            suffix: ''
            build: true
        inheritance:
            - Default
        permissions:
    Admins:
        default: false
        info:
            prefix: ''
            suffix: ''
            build: true
        inheritance:
        permissions:
            - '*'

users:
    ADMIN_NAME:
        group: Admins
        permissions:
    OTHER:
        group: Moderator
        info:
            prefix: ''
            suffix: ''
        permissions:
